摘要： The invention relates to an arrangement and a method in a wire feeding device (L) comprising a frame (1), a hub system (2) arranged to the frame (1) for winding a wire coil (3), and a wire feeding mechanism (4) for pulling the welding wire (10) from the wire coil (3) such that the wire coil (3) rotates in the unwinding direction and for feeding the welding wire (10) through the wire feeding mechanism (4) to a welding torch (5). In the method, in the wire feeding starting stage, the wire feeding mechanism (4) pulls the welding wire (10) into motion and, in the wire feeding stopping stage, the wire feeding mechanism (4) stops pulling the welding wire (10). The hub system (2) comprises means for storing energy, said means for storing energy being adapted to store energy as the wire feeding mechanism (4) starts to pull the welding wire (10) from the wire coil (3) in the unwinding direction such that, when the wire feeding mechanism (4) stops pulling the welding wire (10), the stored energy is adapted to be released, pulling the wire coil (3) in the winding direction, which is the opposite direction in relation to the unwinding direction.

摘要： The object of the invention is a method and an arrangement in a gas shielded arc welding device, such as a MIG/MAG-welder, for reducing the sticking of the wire electrode (1) to the welding current tip (3) of the welding torch (2) in connection with the termination of a welding step. The method utilizes a gas shielded arc welding device comprising a welding torch (2), a power source (4), wire feeding means (5), and a control means (7) for controlling at least the power source (4) and the wire feeding means (5). In connection with the termination of a welding step, a step of switching off the welding current is performed, wherein the welding current is switched off and the electric arc, as a consequence of the welding current being switched off, is extinguished, and a step of stopping the wire feeding is performed, wherein the wire feeding is stopped. After the performing of the step of switching off the welding current and the step of stopping the wire feeding, a step of post stop feeding is performed, wherein the wire electrode (1), by means of the wire feeding means (5), is being moved in relation to the welding current tip (3) of the welding torch (2).
